The plants interact with physical, chemical and biological factors. The plants growing in such a system are subjected to different kinds of influences microorganisms are highly active and most of them are beneficial to plants. The present investigation clearly indicated the addition of bio-inoculants to the experimental crop plant increased their growth over the control. It was evident from this study that Rhizobium sp., Azotobacter sp., Azospirillam sp., can supplement or substitute chemical fertilizers in Cyampsis tetrogoloba and Capsicum annum. The combination of these bio-inoculants can increase the growth. The bio-inoculants also would aid in the growth of native beneficial micro-flora population by producing growth promoting substances and helping in the recycling of nutrients. The bio-fertilizer used would reduce the quantity of the application of the chemical fertilizer to an extent of 30% which makes the cropping process more economical. These symbiotic and asymbiotic nitrogen fixers synthesize the growth promoting substances and enhance the crop productivity and are also helpful combating plant diseases.
